basis ofwhich is made up of copper, nickel,

iron and zinc, with which are mixed certain other metals, whereby the alloy is capable of being rolled, forged, drawn or worked in other ways while the metal is hot. Heretofore alloys of this character, as far as I am aware, have had to be worked by the cold process, that is to say, by annealing from time to time and then working while cold. This alloy can also be worked cold.

In addition to this new alloy being adapted for hot working and cold workin it has the further advantage of being high y resistant to acid. The alloy compr1ses- Copper 40-48 per cent.
